vagrant

Ambiente Docker usando vagrant

Vagrant permite a los usuarios crear y configurar entornos de desarrollo ligeros, reproducibles y portátiles. Vagrant puede trabajar con diferentes proveedores. Por defecto usa virtualbox, pero puedes usar libvirt, VMware, Hyper-V etc.

Ambiente reproducible

• Vagrant usando source uclv

  • Ubuntu 20.04

    Vagranfile

    # -*- mode: ruby -*-
    # vi: set ft=ruby :
    ### Customize
    
    CPU = "1"
    RAM = "1024"
    INTERFACE_BRIDGE = "wlan0"
    
    Vagrant.configure("2") do |config|
    
    config.vm.box = "bento/ubuntu-20.04"
    end
    
    # Port forwarding
    Vagrant.configure("2") do |config|
    
    config.vm.provision "shell", inline: <<-SHELL
    
        sed -i 's/#PermitRootLogin\ prohibit-password/PermitRootLogin\ prohibit-password/' /etc/ssh/sshd_config
        sed -i 's/#PasswordAuthentication\ no/PasswordAuthentication\ no/' /etc/ssh/sshd_config
        service ssh restart
    
        # Add authorized_keys. Escriba su llave y descomente la linea para qe se cargue
        echo "ssh-rsa AAAAB3NzaC1yc2EAAAADA" >> /home/vagrant/.ssh/authorized_keys
    
    ### Set repo Universidad uclv
    sed -i 's/archive.ubuntu.com/repos.uclv.edu.cu/' /etc/apt/sources.list
    sed -i 's/security.ubuntu.com/repos.uclv.edu.cu/' /etc/apt/sources.list
    ## Install docker docker-compose from repo
        apt update && apt upgrade -y && apt install docker.io docker-compose -y
    SHELL
    
    config.vm.network  "public_network", bridge: INTERFACE_BRIDGE  
    #config.vm.network "forwarded_port", guest: 80, host: 8080
    config.vm.provider :virtualbox do |vb|
        vb.customize ["modifyvm", :id, "--cpus", CPU]
        vb.customize ["modifyvm", :id, "--memory", RAM]
    end
    
    end
    

• Vagrant usando source oficial

  • Ubuntu 20.04

    Vagranfile

    # -*- mode: ruby -*-
    # vi: set ft=ruby :
    ### Customize
    
    CPU = "2"
    RAM = "2048"
    INTERFACE_BRIDGE = "wlan0"
    
    Vagrant.configure("2") do |config|
    
    config.vm.box = "bento/ubuntu-20.04"
    end
    
    # Port forwarding
    Vagrant.configure("2") do |config|
    
    config.vm.provision "shell", inline: <<-SHELL
    
        sed -i 's/#PermitRootLogin\ prohibit-password/PermitRootLogin\ prohibit-password/' /etc/ssh/sshd_config
        sed -i 's/#PasswordAuthentication\ no/PasswordAuthentication\ no/' /etc/ssh/sshd_config
        service ssh restart
    
        # Add authorized_keys. Escriba su llave y descomente la linea para qe se cargue
    # echo "ssh-rsa AAAAB3NzaC1yc2" >> /home/vagrant/.ssh/authorized_keys
        
    ## Install docker docker-compose from repo
        apt update && apt upgrade -y && apt install docker.io docker-compose -y
    SHELL
    
    config.vm.network  "public_network", bridge: INTERFACE_BRIDGE  
    #config.vm.network "forwarded_port", guest: 80, host: 8080
    config.vm.provider :virtualbox do |vb|
        vb.customize ["modifyvm", :id, "--cpus", CPU]
        vb.customize ["modifyvm", :id, "--memory", RAM]
    end
    
    end
    

Configuraciones optimizacones

Puede ajustar los recursos que deseara asignar ajustando estas variables del fichero vagrantfile

CPU = "2"
RAM = "2048"
INTERFACE_BRIDGE = "wlan0"

Nota: Si desea cambiar el proveedor a usar. Debe modificar esta linea config.vm.provider :virtualbox do |vb| Escriba el nuevo proveedor que usara

Uso :-)

Levantamos el entorno y accedemos a el.

vagrant up
vagrant ssh
